Step 4: Verify the Block

To verify that the program has been successfully blocked, try to run the program and see if it can access the internet. If the program is unable to connect to the internet, then it has been successfully blocked by the Windows firewall.

You can also check the Windows firewall logs to see if the program has attempted to access the internet. To do this, go back to the Windows Firewall settings and click on the “Advanced settings” link on the left-hand side of the window. Then click on the “Windows Firewall with Advanced Security” link.

In the Windows Firewall with Advanced Security window, click on the “Monitoring” link in the left-hand side of the window, and then click on the “Firewall” link. This will show you a list of all the firewall rules that have been applied, including any rules that block or allow specific programs.

Blocking a program with the Windows firewall is a simple and effective way to control what programs can access the internet. By blocking a program, you can prevent it from using too much bandwidth, prevent it from phoning home, or prevent it from sending data to servers that you don’t trust. With these steps, you can easily block any program that you don’t want to have access to the internet.
